Cable median barriers

The 2010–2013 Statewide Transportation Improvement Program from the Arkansas State Highway and Transportation Department lists cable median barrier installation projects along segments of Interstate 30, I-40, I-55, I-430, Interstate 540, and US 67 to begin as funds become available. The high-tension designs will first be installed in areas with narrow medians that carry an average daily traffic of 15,000 or greater near sites of recent serious crossover collisions.
